1. One one turn turn turn, turn to what?Turn to brush. Brush brush shi shi shi. 转转转，转出什么？转出牙刷。牙刷、牙刷嘶嘶嘶。
2. The basic concept of class D amplifier is to convert the input analog signal into a pulse width modulated signal (PWM signal), then the PWM signal is demodulated to reconstruct the analog signal. 类功率放大器的基本概念就是将欲放大的信号转化为脉宽调制信号，用来驱动开关逆变器。
3. One finger, one finger turn turn turn. Turn to the brush shua shua shua…… 一根手指，一根手指，变，变，变。变成刷子，唰，唰，唰！…
4. The complex apparent conductivity of induction log consists of R-signal (resistive signal) and X-signal (reactive signal), which are defined in uniform medium. 感应测井的实部视电导率（也叫R信号）与虚部视电导率（也叫X信号）构成复视电导率。
5. Time clock signal source directly fetches from clock signal of PCI bus in the computer system or signal generator, which can generates high frequency time clock signal. 该时钟信号源直接取自于该电脑系统中PCI总线的时钟信号或是一可产生高频时钟信号的时钟信号产生器，用以供应该计数电路所需的输入时钟信号。
